[Error] expected primary-expression before '=' token

Your code in the body of the post does not match the code in your attachment, WTF!

You do not do #define inside a function. You have to follow #define something with what it defines
like this

#define JuisteKode noobee

so when ever the pre compiler sees the word JuisteKode it replaces it with noobee before it sends it to the compiler.
